From 61050f75b13ef706d3a80b86137436d3fb0bfa93 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?K=C3=A9vin=20Dietrich?= Date: Sat, 6 Aug 2016 06:20:37 +0200 Subject: Basic Alembic support All in all, this patch adds an Alembic importer, an Alembic exporter, and a new CacheFile data block which, for now, wraps around an Alembic archive. This data block is made available through a new modifier ("Mesh Sequence Cache") as well as a new constraint ("Transform Cache") to somewhat properly support respectively geometric and transformation data streaming from alembic caches. A more in-depth documentation is to be found on the wiki, as well as a guide to compile alembic: https://wiki.blender.org/index.php/ User:Kevindietrich/AlembicBasicIo. Many thanks to everyone involved in this little project, and huge shout out to "cgstrive" for the thorough testings with Maya, 3ds Max, Houdini and Realflow as well as @fjuhec, @jensverwiebe and @jasperge for the custom builds and compile fixes.
